Vehicle Speed Control problem #1

The Kona barely wants to accelerate and stalls out while driving. Even though I recently got a oil change there’s oil consumption and the oil is black as if I never got a oil change. I took it to a Hyundai dealer ship, I told them what was wrong they said it’s the timing belt. When that’s not the issue. I recently took it to a mechanic to get a third opinion and to see and fix what is wrong. He declined fixing it saying there’s more to it that is wrong and looks like there’s an engine defect and even complained that the oil was so black. I told him that doesn’t make sense because I’ve been getting my oil consistently. He couldn’t fix it. So now I’m stuck with a vehicle that barely drives and stalls out while I’m on the road and it keeps burning more oil. No one knows what is wrong with it.

Vehicle Speed Control problem #2

My Kona sputters when I put it in gear every time. I have purchased gas at several stations so getting bad gas in the tank cannot be an issue. I’ve also had to replace the coil packs twice within 6 months. December 2024 and July 2025.
